Flipt v2▲178Hey all, I'm the founder of Flipt, an open-source (https://github.com/flipt-io/flipt) feature flag tool that I (and others) have been working on for the past few years. About a year or two ago we added support for serving flag state from various non-relational declarative stores like Git, OCI, Object Store, etc. Many of our users came to love the git-backed storage, as it allows them to keep their feature flags close to their code in there organization's repos. But they had one (rather large) ask, and that was the ability to use the UI to manage flag state changes and…

Hi HN, I'm the creator of FFlags. I built this because I wanted a feature flagging system that gave me the performance and reliability of an enterprise-scale solution without the months of dev time or the vendor lock-in. The core ideas are: 1. Feature Flags as Code: You define your flag logic in TypeScript. This lets you write complex rules, which felt more natural as a developer myself than using a complex UI for logic. 2. Open Standard: The platform is built on the OpenFeature standard (specifically the Remote Evaluation Protocol). The goal is to avoid vendor lock-in and the usual…

Why? - Decouple application deployment from releases How it works: - Make changes to your features and segments (YAMLs) via Pull Requests - Generate datafile (JSON file) in CI/CD workflow and upload to your CDN - Fetch datafile in your application runtime and consume with SDKs Supports: - Feature flags: boolean flags - Experimentation: a/b tests - Segments: targeting traffic with conditions - Variables: namespaced under each feature and conditional - Gradual rollouts: avoid big bang releases, go from 0% to 100% - Consistent bucketing: same user sees same variation - Multiple…

Hello everyone! To briefly introduce myself, I'm mainly a backend developer, working in the industry for the past 7 years. On one of the products I was working on we were heavily using a custom feature flagging system. Basically, any functionality we were building was starting with a new feature flag. It was useful because: 1. We were able to silently deploy a feature to production for real environment testing 2. We would enable feature flag for specific users across our team, like marketing, sales, so everyone can check it out, test and prepare for the release 3. We were restricting certain…
